APPROVAL of 401 Water Quality Certification with Additional Conditions
Mr. J. B. Setzer, P.E.
Division Engineer
N C Department of Transportation
253 Webster Road
Sylva, North Carolina 28779
Dear Mr. Setzer:
You have our approval, in accordance with the attached conditions and those listed below, to permanently impact 67
linear feet Horse Creek and to temporarily impact Horse Creek with a diversion dike and 120 linear feet of pipe, (67 linear
feet of new double barrel box culvert and construction of a stream diversion dike (60 sq. ft.) and 120 linear feet of
temporary pipe), in order to construct a roundabout at the Intersection of NC Highway 108, Interstate 26 and US Highway
74, in Polk County. The project must be constructed in accordance with the application dated March 4, 2005 (received
March 10, 2005), including the environmental commitments made in the application letter. After reviewing your
application, we have decided that this fill is covered by General Water Quality Certification Nos. 3404 and 3366,
corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 14 and 33. In addition, you must
acquire any other federal, state or local permits before you proceed with your project including (but not limited to)
Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. This approval will expire with
the accompanying 404 Permit unless otherwise specified in the Water Quality Certification.
This approval is valid solely for the purpose and design described in your application (unless modified below). Should
your project.change, you must notify the DWQ in writing and submit a new application. If the property is sold, the new
owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying with all the
conditions. If total wetland fills for this project (now or in the future) exceed one acre, or if total impacts to streams (now
or in the future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any
additional conditions listed below.
1. Erosion and sediment control practices must be in full compliance with all specifications governing the proper design,
installation and operation and maintenance of such Best Management Practices in order to protect surface waters
standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated, and
maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control
Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be
such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina
Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow
sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the
project.

c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated
and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual.
d. The reclamation measures and implementation must comply with the reclamation in accordance with the
requirements of the Sedimentation Pollution Control Act.
2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the
impacts depicted in the Preconstruction Notice Application. All construction activities, including the design,
installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be
performed so that no violations of state water quality standards, statutes, or rules occur.
3. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable.
If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed
and the natural grade restored within six months of the date that the Division of Land Quality has released the project.
4. Adequate sedimentation and erosion control measures should be implemented prior to any ground disturbing activities
to minimize impacts to downstream aquatic resources. Temporary or permanent herbaceous vegetation should be
planted on all bare soil within 15 days of ground disturbing activities to provide long-term erosion control. Erosion
control matting should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian
areas. Matting should be secured in place with staples, stakes or, wherever possible, live stakes of native trees.
Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing
season following completion of construction.
5. Stormwater shall be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site for
the purpose of pre-treating stormwater runoff; and must not be routed directly into streams. Mowing of existing
vegetated buffers is strongly discouraged, so that they may be utilized for stormwater diffuse flow.
6. Culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater than 20% of their size
with the floor of the culvert placed in the main flow channel or thalweg to allow for aquatic life passage. Culverts
that are 48-inch diameter or larger should be buried at least 12 inches below the stream bottom to allow natural stream
bottom material to become established in the culvert following installation and to provide aquatic life passage during
periods of low flow. This may require increasing the size of the culvert to meet flow conveyance requirements. If
any of the existing pipes are perched, they shall be removed and replaced, and re-installed correctly, unless
demonstrated that this is topographically unfeasible. Where more than one pipe or barrel is used, one pipe or barrel
should. be installed to receive normal (base) flow and the other barrel(s) should be modified to receive only flow
during storm events (i.e., level of floodplain bench at or near bankfull elevation). This ensures adequate flow and
water depth in the normal (base) flow barrel, during low and normal flow periods. If box culverts are longer than 40-
50 linear feet, the WRC is requesting alternating or notched baffles be installed in a manner that mimics existing
stream patterns. This type of culvert installation should enhance aquatic life passage by, depositing sediments in the
barrel, maintaining channel depth and flow regimes, and providing a resting place for fish and other aquatic life.
Basically, the normal flow barrel should provide an area with the same water depth, channel width and stream
velocity as the natural stream channel.
7. Removal of vegetation at the stream crossing and adjacent to streams should be minimized. Native trees and shrubs
(e.g. Rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be
planted along the streambank to reestablish the riparian zone and to provide long-term erosion control in the vicinity
of the road crossing and along the streams within dedicated rights of way.
8. Riprap placed for bank stabilization should be limited to the streambank below the high water mark, and
vegetation should be used for stabilization above the high water elevation. Riprap should not be placed in stream
channels in a manner that impedes aquatic life passage.
9. The dimension, pattern and profile of the stream, above and below the culvert, should not be modified by widening
the stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural
geomorphic conditions aquatic life and/or fish passage.
10. Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize
sedimentation and to reduce the likelihood of introducing other pollutants into the stream.
11. All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent
contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
12. Excavation of the stream crossings and relocations should be conducted in the dry, if possible. Sandbags, cofferdams,
flexible pipe or gther diversion structures should be used to minimize excavation in flowing water.
Mr. J. B. Setzer, P.E.
April 7, 2005

13. If concrete is used during culvert installation (e.g., headwalls), a dry work area should be maintained to prevent direct
contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be
discharged to surface waters due to the potential for elevated pH and fish kills.
14. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is
strictly prohibited.
15. The presence of equipment in the channels must be minimized. Under no circumstances must rock, sand or other
materials be dredged from the wetted stream channel under authorization of this pen-nit,. except in the immediate
vicinity of the culverts. Instream dredging has catastrophic effects on aquatic life, and disturbance of the natural form
of the stream channel will likely cause downstream erosion problems, possibly affecting other landowners.
16. Rock check dams at culvert outlets should be removed at project completion to avoid blocking movement of aquatic
life.
17. This certification does not authorize the discharge of waste rock and dirt into.the stream or riparian zone except for
permitted areas associated with culvert conditions.
18. All work shall be performed during low flow conditions (below bankfull).
19. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion" form
to notify the NCDWQ when all work included in the. §401 Certification has been completed. The responsible party
shall complete the attached form and return it to the Transportation Permitting Unit of the NC Division of Water
Quality upon completion of the project. The NCDOT is strongly advised to send in photographs upstream and
downstream of each structure to document correct installation.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act
within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition, which conforms to
Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, N.C. 27699-6714. This certification and its conditions are final and binding unless you ask for a hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have
any questions, please telephone or Mr. Mike Parker of the Asheville Regional Office at 828.296.4500.

Dear Ms. Pennock:
The North Carolina Department of Transportation (NCDOT) proposes to construct a roundabout
in Columbus, North Carolina at the Intersection of NC 108, Interstate 26 and US 74. The
roundabout will serve to maintain traffic flow and eliminate an existing traffic signal. Due to the
traffic volume and congestion at this intersection, NCDOT would like to let a contract for this
work in May 2005.
NCDOT proposes to construct the roundabout at the existing location of the traffic signal. To
gain sufficient area to construct the roundabout, it will be necessary to extend an existing
reinforced concrete box culvert on both the inlet and outlet ends. The culvert conveys Horse
Creek under the existing intersection.
I am attaching a PCN application, site plans with the proposed erosion control and construction
limits, photos, as well as, a marked county map and USGS quad map.
The North Carolina Natural Heritage Database was checked for records of threatened and
endangered species. There are no aquatic species records listed for the Horse Creek watershed or
the adjacent Skyuka Creek and White Oak Creek watersheds. The stream at the culvert site is
somewhat degraded from urbanization and not characteristic of habitat that would support
freshwater mussels.
Roundabout NC 108 Page 2 March 4, 2005
Polk County
There are records for the white irisette (Sisyrinchium dicotomum) within the Horse Creek
watershed above this project along Skyuka Mountain Road. Due to the proximity of the project
site to this known population of white irisette, we requested input from the U.S. Fish and
Wildlife Service (USFWS). Ms. Denise Moldenhauer, Biologist with the USFWS, made a visit
to the site on February 23, 2005. The vegetation at the downstream culvert extension can be
characterized as being overgrown by saplings and briers. The vegetation on the upstream side of
the culvert has a well-developed canopy along the riparian area with a relatively dense understory
and thick litter layer. The USFWS recovery plan states that white irisette habitat consists of
"open, dry to mesic, circumneutral oak-hickory forest communities on mid-elevation mountain
slopes, with aspects ranging primarily from southeast to southwest. On most sites, plants are
exposed to dappled to strong sunlight for at least part of the day." White irisette are found where
the canopy is thin and where much of the deep litter layer ordinarily present on these sites has
been removed. Therefore, while this site is proximal to areas with known populations of white
irisette, the habitat is not characteristic of the habitat described in the USFWS recovery plan or
the occupied habitat along Skyuka Mountain Road. Therefore, based on our site visits and input
from the USFWS, we have concluded that habitat for the white irisette is lacking at this project
site. (See attached email)
Based on the reasons stated above, this project will have "no effect" on threatened and
endangered species.
Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation
Office (SHPO) and the Office of State Archaeology determines that further investigations are
required, NCDOT will conduct the appropriate site investigations and obtain compliance from
SHPO prior to project construction.
Impacts to Waters of the United States
Horse Creek is considered a perennial stream with a well-defined channel and is shown on the
USGS topographic maps as a blue line stream. The channel is composed of sand and gravel
substrate and lacks vegetation. The stream is of sufficient size to support fish and other aquatic
organisms. Therefore, we believe that Horse Creek is under the jurisdictional authority of the US
Army Corps of Engineers. In order to construct the project it may be necessary to impact waters
of the United States in the Broad River Basin. Specifically, NCDOT is requesting to extend the
existing culverts in Horse Creek (DWQ Class Q. Listed below is a summary of the proposed
impacts.

Erosion and sedimentation control measures that are sufficient to protect surface waters will be
used on this project to minimize impacts to downstream aquatic resources. The construction
foreman will review all erosion control measures daily to ensure sedimentation and erosion is
being effectively controlled.

information related to site constraints such as topography, building ordinances, accessibility, and
financial viability of the project. The applicant may attach drawings of alternative, lower-impact
site layouts, and explain why these design options were not feasible. Also discuss how impacts
were minimized once the desired site plan was developed. If applicable, discuss construction
techniques to be followed during construction to reduce impacts.
The culverts are being extended the minimum amount to gain the necessary space to
construct the roundabout. Due to the existing roads, adjacent businesses and creek, realignment
of the intersection is not possible.

DWQ - In accordance with 15A NCAC 2H .0500, mitigation may be required by the NC
Division of Water Quality for projects involving greater than or equal to one acre of impacts to
freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
streams.
USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide
Permits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects to the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in. determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
aquatic resource functions and values by creating, restoring, enhancing, or preserving similar
functions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCEEP concurrence shall be placed on hold as incomplete.
An applicant may also choose to review the current guidelines for stream restoration in DWQ's
Draft Technical Guide for Stream Work in North Carolina, available at
hLtp://h2o.enr.state.nc.us/ncwetlands/strmgide.htiml.

Owen,
After reviewing the pictures of the lower end of the project, the 41 foot extension, it is obvious that no suitable
habitat exists for the white irisette. After our site review of the upper extension I believe there is no suitable habitat
within this area for white irisette. The recovery plan states that white irisette habitat consists of "open, dry to
mesic, circumneutral oak-hickory forest communities on mid-elevation mountain slopes, with aspects ranging
primarily from southeast to southwest. On most sites, plants are exposed to dappled to strong sunlight for at least
part of the day." White irisette are found where the canopy is thin and where much of the deep litter layer
ordinarily present on these sites has been removed. The habitat we saw had a fairly thick canopy and understory
and the litter layer seemed to be thick. Therefore I believe you can make the determination that this project would
have no effect on white irisette due to lack of habitat.

Inspection on January 17, 2007. Box culvert has been extended and some fill material has been placed
on both sides of NC 108. Temporary seeding, mulching and matting are in place. It appears that the
project is on hold at the present time. Culvert appears to be installed correctly. There is no head
cutting on inlet end. Sediment and erosion control devices have recently been cleaned. Periodic
inspections should be conducted of site to ensure that no sediment is leaving the construction area.
